Value Delivered
ECM provided restoration services and protective coatings for 110 HVAC units across 57 buildings at the Fort Riley U.S. Army base. In collaboration with our ESCO client, our rejuvenation process helped protect the existing equipment against future corrosion and restored it to near its original efficiency, with a simple payback of 3.38 years.
After the project was complete, we performed measurement and verification that estimated energy savings of $147,000 per year—34-percent higher than initial projections. We also calculated an additional $99,000 of savings generated by reducing the amount of labor required to pay their third-party maintenance team and by avoiding costs associated with equipment replacement.
Client Objectives
The client wanted to extend the useful lifespan and improve the performance of deteriorating, air-cooled HVAC systems that were prematurely aged from harsh environmental conditions.
Solutions
Our seven-step rejuvenation process included removing existing corrosion and debris, addressing fin and coil deterioration, applying our proprietary HVAC Armor coating, and optimizing the refrigerant system by eliminating oil build up and filter blockages.

Steps 2 and 3: Coil/Fin Service and Deep Clean
- Remove housings and casings
- Clean and straighten fins
- Deep clean coils from both sides
Steps 4 and 5: Equipment Prep and Coating
- Mask off areas that do not need coating
